I've done CD a few times and never been interested in this, but I bought some on saturday, cant believe how nice it is! A tub does @17? servings I can see I will be buying some more in a fortnight! Last night I put my water in the freezer for 10 mins before mixing the shake in, it then only took 5 mins in the fridge to set. I sometimes feel like I'm drowning in water/shakes/soup but I felt like I was eating with this.
